A Dallas man was arrested for sexually assaulting his two young family members Thursday night, police say.

Antonio Lopez Manzilla, 38, was charged with two counts of indecency with a child by sexual contact. He remains in the Dallas County jail in lieu of $200,000 bail.

Manzilla was left alone with two family members, ages 5 and 8, early Thursday afternoon at a home in the 6800 block of Shady Brook Lane in Northeast Dallas. The girls’ mother left the home to go grocery shopping. When she returned, the girls told her Manzilla assaulted them, according to an arrest warrant.

The mother left the home with her daughters and called police. During police interviews, both girls recounted how Manzilla had inappropriately touched them. He was arrested around 7:30 p.m., according to police records.
